Any two successive gauges (e.g., A and B) have diameters whose ratio (dia. B ÷ dia. A) is (approximately 1.12293), while for gauges two steps apart (e.g., A, B, and C), the ratio of the C to A is about 1.12293 2 ≈ 1.26098. Similarly for gauges n steps apart the ratio of the first to last gauges is about 1.12293 n.
